[Elecraft] New KSYN3a installed and not working / recognized

[N2ZDB at aol.com]

My KREF3 board needed R12 to be changed from 150 to 51 Ohms, even though I  
only have the K144XV option and not also the sub receiver.
 
Problem fixed!

Michael,

Check and recheck the plugging of the TMP cables.  Make sure the TMP 
connectors are fully seated.  The cables must match  that shown in Figure 
12 on page 16 of the installation  instructions.

Did you exit the menu after turning Tech Mode on?   If not, you need to 
do that and try again.

If no luck, contact  Elecraft support for additional help and resolution.
